In modern mechanical engineering, the number of parts with spatially complex surfaces is growing, the shape of which is determined analytically according to certain criteria. They are most widely used in the energy, aviation, tool industries (turbine blades, unicycles). With the current practice of processing such parts on CNC machines, when developing control programs, the analytically calculated shape of the surfaces is replaced by an approximate graphical model, which is used to calculate tool trajectories. This practice is due to the historically existing in the 1970-90s the capabilities of electronics and electrically driven devices. Despite the fundamentally new modern possibilities of computer control and electric drive devices, CNC machines retained the traditional initial principle of surface shaping using approximation and interpolation methods. At the same time, already at the stage of technological preparation of control programs, certain assumptions and losses in accuracy are assumed. The solution of this problem is relevant in connection with the current trend of increasing requirements for the accuracy of critical parts with spatially complex surfaces. The article proposes the principle of alternative control of shaping feeds when milling parts with spatially complex surfaces using the form of specifying the surface in an analytical form. The application of this principle excludes intermediate stages associated with the transformation of the analytical form of the task into a graphic one, the choice of coordinates of reference points and the interpolation of elementary sections. It is proposed, based on the proposed functional relationship between the geometric shape of a spatially complex surface and the established ratio of the components of the contour feed, based on the use of modern capabilities of computing devices and an electric drive, to provide a fundamentally new approach to shaping. The use of the proposed approach ensures complete automation of the preparation of control programs. [ABSTRACT FROM AUTHOR]

Objectives: Canada has one of the highest age-adjusted incidence and prevalence rates of inflammatory bowel disease (IBD). Large patient volumes and limited resources have created challenges concerning the quality of IBD care, but little is known about patients' experiences. This paper aimed to better understand patient-perceived barriers to IBD care., Methods: An exploratory qualitative approach was used for this study. Fourteen focus groups (with 63 total participants) were co-facilitated by a researcher and patient research partner across eight Canadian provinces in 2018. Patients diagnosed with IBD (>18 years of age) and their caregivers were purposefully recruited through Crohn's and Colitis Canada, gastroenterology clinics and communities, and national social media campaigns. Focus group sessions were recorded, transcribed, and analyzed using thematic analysis., Results: Most participants self-identified as being white and women. The analysis generated four key themes regarding patient-perceived barriers and gaps in access to IBD care: (1) gatekeepers and their lack of IBD knowledge, (2) expenses and time, (3) lack of holistic care, and (4) care that is not patient-centered. An additional four themes were generated on the topic of patient-perceived areas of health system improvement for IBD care: (1) direct access to care, (2) good care providers, (3) electronic records and passports, and (4) multidisciplinary care or an 'IBD dream team'., Conclusions: This research contributes to the limited global knowledge on patients' experiences accessing IBD care. It is valuable for the development of care plans and policies to target gaps in care. Patients have identified system-level barriers and ideas for improvement, which should be taken into consideration when implementing system redesign and policy change., Competing Interests: Declaration of conflicting interestsThe authors declare that there are no conflicts of interest.

Background: Coronary artery disease (CAD) confers increased risks of premature mortality, non-fatal morbidity, and significant impairment in functional status and health-related quality of life. Routine administration of electronic patient-reported outcome measures (PROMs) and its real time delivery to care providers is known to have the potential to inform routine cardiac care and to improve quality of care and patient outcomes. This study describes a user-centered development and evaluation of the Alberta Provincial Project for Outcomes Assessment (APPROACH) electronic Patient Reported Outcomes Measurement (e-PROM) system. This e-PROM system is an electronic system for the administration of PROMs to patients with CAD and the delivery of the summarized information to their care providers to facilitate patient-physician communication and shared decision-making. This electronic platform was designed to be accessible via web-based and hand-held devices. Heuristic and user acceptance evaluation were conducted with patients and attending care providers., Results: The APPROACH e-PROM system was co-developed with patients and care providers, research investigators, informaticians and information technology experts. Five PROMs were selected for inclusion in the online platform after consultations with patient partners, care providers, and PROMs experts: the Seattle Angina Questionnaire, Patient Health Questionnaire, EuroQOL, and Medical Outcomes Study Social Support Survey, and Self-Care of Coronary Heart Disease Inventory. The heuristic evaluation was completed by four design experts who examined the usability of the prototype interfaces. User acceptance testing was completed with 13 patients and 10 cardiologists who evaluated prototype user interfaces of the e-PROM system., Conclusion: Both patients and physicians found the APPROACH e-PROM system to be easy to use, understandable, and acceptable. The APPROACH e-PROM system provides a user-informed electronic platform designed to incorporate PROMs into the delivery of individualized cardiac care for persons with CAD., (© 2024. The Author(s).)

Background: There is evidence supporting the value of patient engagement (PE) in research to patients and researchers. However, there is little research evidence on the influence of PE throughout the entire research process as well as the outcomes of research engagement. The purpose of our study is to add to this evidence., Methods: We used a convergent mixed method design to guide the integration of our survey data and observation data to assess the influence of PE in two groups, comprising patient research partners (PRPs), clinicians, and researchers. A PRP led one group (PLG) and an academic researcher led the other (RLG). Both groups were given the same research question and tasked to design and conduct an inflammatory bowel disease (IBD)-related patient preference study. We administered validated evaluation tools at three points and observed PE in the two groups conducting the IBD study., Results: PRPs in both groups took on many operational roles and influenced all stages of the IBD-related qualitative study: launch, design, implementation, and knowledge translation. PRPs provided more clarity on the study design, target population, inclusion-exclusion criteria, data collection approach, and the results. PRPs helped operationalize the project question, develop study material and data collection instruments, collect data, and present the data in a relevant and understandable manner to the patient community. The synergy of collaborative partnership resulted in two projects that were patient-centered, meaningful, understandable, legitimate, rigorous, adaptable, feasible, ethical and transparent, timely, and sustainable., Conclusion: Collaborative and meaningful engagement of patients and researchers can influence all stages of qualitative research including design and approach, and outputs., (© 2024.

Background: Inclusiveness, Support, Mutual Respect and Co-Build are the four pillars of patient engagement according to the Strategy for Patient-Oriented Research (SPOR). The aim of this manuscript is to describe the operationalization of these principles through the creation of a Patient Advisory Council (PAC) for the research study titled 'Re-Purposing the Ordering of Routine laboratory Tests (RePORT)'., Methods: Researchers collaborated with the Alberta SPOR SUPPORT Unit (AbSPORU) Patient Engagement Team to create a diverse PAC. Recruitment was intentional and included multiple perspectives and experiences. PAC meetings were held monthly, and patient research partners received support to function as co-chairs of the PAC. Patient research partners were offered training, support and tailored modalities of compensation to actively engage with the PAC. Regular member check-ins occurred through reflexivity and a formal evaluation of PAC member engagement., Results: The PAC included between 9 and 11 patient research partners, principal investigator, research study coordinator, improvement scientist, resident physician and support members from the AbSPORU team. Twelve monthly PAC meetings were held during the first phase of the project. The PAC made course-changing contributions to study design including study objectives, recruitment poster, interview guide and development of codes for thematic analysis. Patient research partners largely felt that their opinions were valued. Diversity in the PAC membership enhanced access to diverse patient participants. Furthermore, support for co-chairs and patient research partner members enabled active engagement in research. In addition, a culture of mutual respect facilitated patient partner engagement, and co-design approaches yielded rich research outputs., Conclusions: Collaboration between research teams and Patient Engagement Teams can promote effective patient engagement through a PAC. Deliberate and flexible strategies are needed to manage the PAC to create an ecology of Inclusiveness, Support, Mutual Respect, and Co-Build for meaningful patient engagement., Patient or Public Contribution: Patient research partners were involved in the decision to write this manuscript and collaborated equitably in the conception and development of this manuscript, including providing critical feedback. Patient research partners were active members of the PAC and informed the research project design, participant recruitment strategies, data collection and analysis, and will be involved in the implementation and dissemination of results. They are currently involved in the co-development of a patient engagement strategy using a Human-Centered Design process., (© 2023 The Authors.

Background: Studies report various ways in which patients are involved in research design and conduct. Limited studies explore the influence of patient engagement (PE) at each research stage in qualitative research from the perspectives of all stakeholders., Methods: We established two small research groups, a Patient Researcher-Led Group and an Academic Researcher-Led Group. We recruited patient research partners (PRP; n = 5), researchers ( n = 5), and clinicians ( n = 4) to design and conduct qualitative research aimed at identifying candidate attributes related to patient preferences for tapering biologic treatments in inflammatory bowel disease. We administered surveys before starting, two months into, and post-project work. The surveys contained items from three PE evaluation tools. We assessed the two groups regarding the influence and impact each stakeholder had during the different research stages., Results: PRPs had a moderate or a great deal of influence on the critical research activities across the research stages. They indicated moderate/very/extremely meaningful engagement and agreed/strongly agreed impact of PE. PRPs helped operationalize the research question; design the study and approach; develop study materials; recruit participants; and collect and interpret the data., Conclusion: The three tools together provide deeper insight into the influence of PE at each research stage. Lessons learnt from this study suggest that PE can impact many aspects of research including the design, process, and approach in the context of qualitative research, increasing the patient-centeredness of the study. More comprehensive validated tools are required that work with a more diverse subject pool and in other contexts., Competing Interests: Deborah A.

Objective: The objective of this study was to explore the outcomes of research engagement (patient engagement, PE) in the context of qualitative research., Design: We observed engagement in two groups comprised of patients, clinicians and researchers tasked with conducting a qualitative preference exploration project in inflammatory bowel disease. One group was led by a patient research partner (PLG, partner led group) and the other by an academic researcher (RLG, researcher led group). A semistructured guide and a set of critical outcomes of research engagement were used as a framework to ground our analysis., Setting: The study was conducted online., Participants: Patient research partners (n=5), researchers (n=5) and clinicians (n=4) participated in this study., Main Outcome Measures: Transcripts of meetings, descriptive and reflective observation data of engagement during meetings and email correspondence between group members were analysed to identify the outcomes of PE., Results: Both projects were patient-centred, collaborative, meaningful, rigorous, adaptable, ethical, legitimate, understandable, feasible, timely and sustainable. Patient research partners (PRPs) in both groups wore dual hats as patients and researchers and influenced project decisions wearing both hats. They took on advisory and operational roles. Collaboration seemed easier in the PLG than in the RLG. The RLG PRPs spent more time than their counterparts in the PLG sharing their experience with biologics and helping their group identify a meaningful project question. A formal literature review informed the design, project materials and analysis in the RLG, while the formal review informed the project materials and analysis in the PLG. A PRP in the RLG and the PLG lead leveraged personal connections to facilitate recruitment. The outcomes of both projects were meaningful to all members of the groups., Conclusions: Our findings show that engagement of PRPs in research has a positive influence on the project design and delivery in the context of qualitative research in both the patient-led and researcher-led group., Competing Interests: Competing interests: DAM discloses consulting fees from the Office for Health Economics, Novartis and Analytica during the conduct of this study.

Background: In patient-oriented research (POR), patients contribute their valuable knowledge and lived-experiences to work together as active research partners at all stages of the health research cycle. However, research looking to understand how patient research partners (PRPs) and researchers work together in meaningful and collaborative ways remains limited. This study aims to evaluate patient engagement with the RePORT Patient Advisory Council (PAC) and to identify barriers and facilitators to meaningful patient engagement encountered within research partnerships involving patient research partners and researchers., Methods: The RePORT PAC members included nine PRPs and nine researchers (clinician-researchers, research staff, patient engagement experts) from both Alberta and British Columbia. All members were contacted and invited to complete an anonymous online survey (Public and Patient Engagement Evaluation (PPEET) tool) at two different project times points. The PAC was invited for a semi-structured interview to gain in-depth understanding of their experiences working together. Interviews were audio-recorded, transcribed, and the data was thematically analyzed with the support of a qualitative analysis software, NVivo., Results: A total of nine PRPs (100%) and three researchers (33%) participated in the baseline survey in February 2022 while six PRPs (67%) responded and three researchers (33%) completed the follow up survey in May 2022. For the semi-structured interviews, nine PRPs (100%) and six researchers (67%) participated. According to the survey results, PAC members agreed that the supports (e. g. training, compensation) needed to contribute to the project were available throughout the project. The survey responses also showed that most members of the PAC felt their opinions and views were heard. Responses to the survey regarding diversity within the PAC were mixed. There were many suggestions for improving diversity and collaboration provided by PAC members during the semi-structured interviews. PAC members mentioned that PAC PRPs informed the co-development of research materials such as recruitment posters and interview guides for the RePORT study., Conclusions: Through fostering a collaborative environment, we can engage a diverse group of people to work together meaningfully in health research. We have identified what works well, and areas for improvement within our research partnership involving PRPs and researchers as well as recommendations for POR projects more broadly, going forward., (© 2023.

Introduction: Patient engagement in patient-oriented research (POR) is described as patients collaborating as active and equal research team members (patient research partners [PRPs]) on the health research projects and activities that matter to them. The Canadian Institutes of Health Research (CIHR), Canada's federal funding agency for health research, asks that patients be included as partners early, often and at as many stages of the health research process as possible. The objective of this POR project was to co-build an interactive, hands-on training programme that could support PRPs in understanding the processes, logistics and roles of CIHR grant funding applications. We also conducted a patient engagement evaluation, capturing the experiences of the PRPs in co-building the training programme., Methods: This multiphased POR study included a Working Group of seven PRPs with diverse health and health research experiences and two staff members from the Patient Engagement Team. Seven Working Group sessions were held over the 3-month period from June to August 2021. The Working Group worked synchronously (meeting weekly online via Zoom) as well as asynchronously. A patient engagement evaluation was conducted after the conclusion of the Working Group sessions using a validated survey and semi-structured interviews. Survey data were analysed descriptively and interview data were analysed thematically., Results: The Working Group co-built and co-delivered the training programme about the CIHR grant application process for PRPs and researchers in five webinars and workshops. For the evaluation of patient engagement within the Working Group, five out of seven PRPs completed the survey and four participated in interviews. From the survey, most PRPs agreed/strongly agreed to having communication and supports to engage in the Working Group. The main themes identified from the interviews were working together-communication and supports; motivations for joining and staying; challenges to contributing; and impact of the Working Group., Conclusion: This training programme supports and builds capacity for PRPs to understand the grant application process and offers ways by which they can highlight the unique experience and contribution they can bring to each project. Our co-build process presents an example and highlights the need for inclusive approaches, flexibility and individual thinking and application., Patient or Public Contribution: The objective of this project was to identify the aspects of the CIHR grant funding application that were elemental to having PRPs join grant funding applications and subsequently funded projects, in more active and meaningful roles, and then to co-build a training programme that could support PRPs to do so. We used the CIHR SPOR Patient Engagement Framework, and included time and trust, in our patient engagement approaches to building a mutually respectful and reciprocal co-learning space. Our Working Group included seven PRPs who contributed to the development of a training programme. We suggest that our patient engagement and partnership approaches, or elements of, could serve as a useful resource for co-building more PRP-centred learning programmes and tools going forward., (© 2023 The Authors.

Background: Strategies incorporating objective disease monitoring in Crohn's disease (CD), beyond clinical symptoms are important to improve patient outcomes. Little evidence exists to explore patient understanding of CD treatment goals, nor preferences and experiences with monitoring options. This qualitative study aimed to explore patient experiences and preferences of CD monitoring to inform monitoring strategies, improve patient engagement, and optimize a patient-centered approach to care., Methods: This study used a patient-oriented, qualitative descriptive design. Convenience and snowball sampling were used to recruit adult participants diagnosed with CD who had experience with at least 2 types of disease monitoring. Online focus groups were conducted and data were analyzed using thematic analysis., Results: This international study included 37 participants from Australia, Canada, United Kingdom, and the United States. Overall, participants preferred more noninvasive types of monitoring [eg, intestinal ultrasound (IUS)] but were willing to undergo more invasive monitoring (eg, colonoscopy) if required. To improve disease monitoring, participants wanted increased access to IUS, establishment of a patient-centered interdisciplinary team and access to information and self-testing. Participants identified challenges with communication between patients and providers and stressed the importance of participating in shared decision making and being equal team members in their care., Conclusions: It is imperative to incorporate patient-driven preferences into how we can best structure monitoring strategies, to ensure equitable access to those preferred modalities and embrace a shared decision-making approach to disease management in CD., Competing Interests: N.R., S.Z., and S.R. declare no conflict of interest.

Objective: To develop a set of patient and family engagement indicators (PFE-Is) for measuring engagement in health system improvement for a Canadian provincial health delivery system through an evidence-based consensus approach., Design: This mixed-method, multiphase project included: (1) identification of existing measures of patient and family engagement through a review of the literature and consultations with a diverse provincial council of patients, caregivers, community members and researchers. The Public and Patient Engagement Evaluation Tool (PPEET) was selected; (2) consultations on relevance, acceptability and importance with patient and family advisors, and staff members of Alberta Health Services' Strategic Clinical Networks. This phase included surveys and one-on-one semi-structured interviews aimed to further explore the use of PPEET in this context. Findings from the survey and interviews informed the development of PFE-Is; (3) a Delphi consensus process using a modified RAND/UCLA Appropriateness Method to identify and refine a core set of PFE-Is., Participants: The consensus panel consisted of patients, family members, community representatives, clinicians, researchers and healthcare leadership., Results: From an initial list of 33 evidence-based PFE-Is identified, the consensus process yielded 18 final indicators. These PFE-Is were grouped into seven themes: communication, comfort to contribute, support needed for engagement, impact and influence of engagement initiative, diversity of perspectives, respectful engagement, and working together indicators., Conclusions: This group of final patient, family and health system leaders informed indicators can be used to measure and evaluate meaningful engagement in health research and system transformation. The use of these metrics can help to improve the quality of patient and family engagement to drive health research and system transformation., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Canada has the highest global age-adjusted incidence and prevalence rates of inflammatory bowel disease (IBD). Due to IBD patient volumes and limited resources, challenges to timely access to specialty care have emerged. To address this gap, the aim of this paper was to understand the experiences and perspectives of persons living with IBD with a focus on accessing health care., Methods: Using a qualitative descriptive approach, patients diagnosed with IBD (≥18 years of age) were purposively sampled from rural and urban gastroenterology clinics and communities across Canada. Co-facilitated by a researcher and patient research partner, 14 focus groups were recorded, transcribed, and coded for themes. Thematic analysis was used to ascertain the congruence or discordance of IBD specialty care access experiences., Results: A total of 63 individuals participated in the study. The majority of participants were female (41/63, 65%) and from urban/suburban regions (33/63, 52%), with a mean age of 48.39 (range 16-77 years). The analysis generated three main themes: (1) need for patient to be partner, (2) adapting IBD care access to individual context, and (3) patient-defined care priorities should guide access to IBD care., Conclusions: The complexity of specialty care access for IBD patients cannot be underestimated. It is vital to possess a robust understanding of healthcare system structures, processes, and the impact of these factors on accessing care. Using a patient-centered exploration of barriers and facilitators, IBD specialty care access in Canada can be better understood and improved on provincial and national levels., (© The Author(s) 2022.

The prevalence of inflammatory bowel diseases (IBD), Crohn's disease and ulcerative colitis, in Canada, is over 0.75% in 2021. Many individuals with IBD are immunocompromised. Consequently, the World Health Organization's declaration of a global pandemic uniquely impacted those with IBD. Crohn's and Colitis Canada (CCC) formed the COVID-19 and IBD Taskforce to provide evidence-based guidance during the pandemic to individuals with IBD and their families. The Taskforce met regularly through the course of the pandemic, synthesizing available information on the impact of COVID-19 on IBD. At first, the information was extrapolated from expert consensus guidelines, but eventually, recommendations were adapted for an international registry of worldwide cases of COVID-19 in people with IBD. The task force launched a knowledge translation initiative consisting of a webinar series and online resources to communicate information directly to the IBD community. Taskforce recommendations were posted to CCC's website and included guidance such as risk stratification, management of immunosuppressant medications, physical distancing, and mental health. A weekly webinar series communicated critical information directly to the IBD community. During the pandemic, traffic to CCC's website increased with 484,755 unique views of the COVID-19 webpages and 126,187 views of the 23 webinars, including their video clips. CCC's COVID-19 and IBD Taskforce provided critical guidance to the IBD community as the pandemic emerged, the nation underwent a lockdown, the economy reopened, and the second wave ensued. By integrating public health guidance through the unique prism of a vulnerable population, CCC's knowledge translation platform informed and protected the IBD community., (© The Author(s) 2021.

Persons with inflammatory bowel disease (IBD) make up more than 0.75% of the Canadian population in 2021. Early in the COVID-19 pandemic, individuals with IBD, particularly those on immunosuppressive therapies, were concerned that their health status may place them at higher risk of contracting COVID-19 or experiencing more severe disease course if infected with SARS-CoV-2. In response, Crohn's and Colitis Canada developed the COVID-19 and IBD Taskforce in March 2020 to rapidly synthesize the evolving knowledge of COVID-19 as relevant to Canadians with IBD. The Taskforce communicated expert information directly to the Canadian IBD community through online tools and a webinar series. In order to understand the full impact of COVID-19 on the IBD community, Crohn's and Colitis Canada commissioned a policy report that was informed through a systematic literature review and synthesized across working groups along the following domains: Epidemiology, Children and Expectant Mothers with IBD, Seniors with IBD, Mental Health, Risk Factors and Medications, Vaccines, and Healthcare Delivery during the Pandemic and the Future Model of IBD Care. This report from Canadian physicians, researchers, and IBD community representatives highlights the physical, mental, and health systems impact of COVID-19 on the entire spectrum of the IBD community, including children, adolescents, adults, seniors, and pregnant people with IBD. This executive summary provides an overview of the crucial information from each of the chapters of the policy report, supplemented with additional information made available through Crohn's and Colitis Canada's webinar-based knowledge translation platform., (© The Author(s) 2021.
